Hi and welcome to the forum! I am glad that I can help you.
You would like to know whether you might have any medical condition.
Once food is ingested it is processed in the gaster(stomach). As the food is mixed up with the stomach acid, the stomach muscles start the movement(peristalsis) which can be rather strong to initiate bowel movement and defecation. Sometimes spicy or overly sweet food may cause a bowel movement and defecation. Tea and coffee are stimulants that not only increase blood pressure, but initiate the bowel movement.
According to the data that you described, it is not likely that you are experiencing any medical condition. See an infectologist if you experience pain, bowel movements and diarrhea. You may also consider seeing a gastroenterologist if you experience diarrhea with an uncontrollable need to defecate or feces mixed with pus or blood to rule out conditions like Chron's disease or ulcerative colitis.
Please keep in mind that I provide medical information only. I am not able to diagnose medical conditions online. Please contact your doctor or other qualified healthcare provider such as an infectologist or a gastroenterologist for further advice and information about your current condition.
